This option adds the content of a rootfs on a specific location on the
rootfs.
It is very useful for making a partition that contains the rootfs for a
host and a target Eg:
/ -> Roofs for the host
/export/ -> Rootfs for the target (which will netboot)
Although today we support making a partition for "/export" this might
not be compatible with some upgrade systems, or we might be limited by
the number of partitions.
With this patch we can use something like:
part / --source rootfs --embed-rootfs target-image /export --embed-rootfs target-image2 /export2
on the .wks file.

APPEND is used to add additional parameters to kernel by features, such
as read-only-rootfs. So we should honor this variable when we compose
the kernel parameter in wic. I know we also can resolve this kind of
issue by using the .wks.in template introduced by commit 42e870c5ed4b
("image_types.bbclass: support template .wks.in files for wic"), but the
APPEND is needed by all the wks, it would seems pretty ridiculous to me
to change all the .wks to .wks.in and then foist the APPEND into them.
So the APPEND is definitely deserved to export to the wic directly.

This option adds the contents of the given path to a partition built
with the rootfs source plugin. The path is relative to the directory in
which wic is running not the rootfs itself so use of an absolute path
is recommended. This option is most useful when multiple copies of the
rootfs are added to an image and it is required to add extra content to
only one of these copies. This option only has an effect with the
rootfs source plugin.

In order to create a msdos partition table disk image that can auto
expand after the image is copied to an SD card, wic needs the ability
to have a primary partition as the last entry. The desired use case
is to be able to create an A/B update partition image scheme with a
/var volume that can be auto expanded to the remainder of the SD card
at run time.
The typical .wks file will look similar to the following:
bootloader --ptable msdos
part / --source rawcopy --sourceparams="file=u-boot.imx" \
--ondisk mmcblk --no-table --align 1 --size 1
part /boot --source bootimg-partition \
--ondisk mmcblk --fstype=vfat --label boot --active --align 4 --size 16
part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \
--ondisk mmcblk --fstype=ext4 --label otaboot --align 4 --type logical
part / --source rawcopy --sourceparams="file=imx6.otaimg" \
--ondisk mmcblk --fstype=ext4 --label otaroot --align 4 --type logical
part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \
--ondisk mmcblk --fstype=ext4 --label otaboot_b --align 4 --type logical
part / --source rawcopy --sourceparams="file=imx6.otaimg" \
--ondisk mmcblk --fstype=ext4 --label otaroot_b --align 4 --type logical
part /var --source rawcopy --sourceparams="file=imx6_var.otaimg" \
--ondisk mmcblk --fstype=ext4 --label fluxdata --align 4
Without the patch applied, wic will generate an SD card image that looks like:
Disk boot.img: 890940s
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 2056s 48001s 45946s primary fat16 lba
2 48008s 132467s 84460s primary ext4
3 132472s 454467s 321996s primary ext4

5 454472s 538931s 84460s logical ext4
6 538936s 860931s 321996s logical ext4
7 860936s 890939s 30004s logical ext4 boot
With the patch applied a primary partition can be created at the end
of the image which can be expanded to fill the free space on the media
where the image has been copied, which looks like:
Disk boot.img: 890940s
Sector size (logical/physical): 512B/512B
Partition Table: msdos

This adds SPDX license headers in place of the wide assortment of things
currently in our script headers. We default to GPL-2.0-only except for the
oeqa code where it was clearly submitted and marked as MIT on the most part
or some scripts which had the "or later" GPL versioning.
The patch also drops other obsolete bits of file headers where they were
encoountered such as editor modelines, obsolete maintainer information or
the phrase "All rights reserved" which is now obsolete and not required in
copyright headers (in this case its actually confusing for licensing as all
rights were not reserved).
More work is needed for OE-Core but this takes care of the bulk of the scripts
and meta/lib directories.
The top level LICENSE files are tweaked to match the new structure and the
SPDX naming.

image_types_wic.bbclass has a mechanism for doing variable substitution
on .wks files by simply letting the input file be called
.wks.in. However, that doesn't allow using variables in files included
via the include directive. This is unfortunate, because lacking either
the ability to include other files or variable substitution leads to
fragile and error-prone duplication between kickstarter files and
recipes/configuration files used for various boards.
This adds (somewhat naive) support for variable substitution in all
files parsed by wic. The user should add all required variables to
WICVARS to get them exported appropriately.

wic allows the user to create disk image and reference each created
partitions via its partition UUID.
squashfs does not support filesystem UUID but it does offer support for
partition UUID.

Modifying this constrain allows a user to create squashfs-based rootfs and boot
from them with such kernel argument 'root=PARTUUID=7d46da2d-29cc-4d5a-9e39-d0381c4abb0c'

First, allow for wic to be given a filesystem UUID to be used when
creating a filesystem. When not provided, wic will generate the UUID to
be used. Next, when --use-uuid is passed, we update the fstab to mount
things via UUID (and if not found, then use PARTUUID) as UUID is more
portable.

It will omit the given path from the resulting partition, and if the
given path ends in a slash, it will only delete the content, and keep
the directory.
Since mkfs only accepts whole directories as input, we need to copy
the rootfs directory to the workdir so that we can selectively delete
files from it.
Since we want to use the copyhardlinktree() function, we need to put
the generic oe lib in the module search path.

Added new option --fixed-size to wks. The option can be used to indicate
the exact size of a partition. The option cannot be added together with
--size, in which case an error will be raised. Other options that
influence automatic partition size (--extra-space, --overhead-factor),
if specifiec along with --fixed-size, will raise an error.
If it partition data is larger than the amount of space specified with
--fixed-size option wic will raise an error.

A kickstart file for non-x86 boards may have no 'bootloader' stanza. It
is the usual case if bootloader is setup using other mechanism than
through wic, and is for instance a part of u-boot configuration. In such
case the 'bootloader' field in the KickStart class will be
uninitialized. Instead of adding an empty bootloader line in every
kickstart file call the bootloader parser with empty argument list to
get defaults namespace.
